We are a faith-forward team dedicated to making a difference in the world.

Dr. Gicheru and his close friend Dr. Olatunji founded GCO with the initial intent of supporting international medical mission teams. What started as a simple venture has blossomed into a robust faith-based organization that serves those in greatest need in the United States and overseas.

Through a series of divine alignments and the dedication of friends, volunteers and donors, GCO has grown into an organization that truly strives to fulfill the Great Commission.
